在做项目中，处理完各种业务数据后都需要返回值告诉前端最后的操作结果，但又不能直接返回一串错误代码信息，这个时候结果处理工具类就起了有比较好的作用。

       在此记录下，比较简单返回结果处理方法供大家参考学习

1.结果返回处理业务类

package result;

public class ResponseData{

    private String result_code;
    private String msg;
    private Object data;

    public String getResult_code(){return result_code;}
    public void   setResult_code(){this.result_code = result_code;}
    public String getMsg(){return msg;}
    public void   setMsg(){this.msg=msg;}
    public Object getData(){return data;}
    public void   setData(){this.data= data;}
    public ResponseData() {
    }

    public ResponseData(String result_code, String msg) {
        this.result_code= result_code;
        this.msg = msg;
    }

    public ResponseData(String result_code, String msg, String data) {
        this.result_code = result_code;
        this.msg = msg;
        this.data = data;
    }

    /**
     * 默认的成功
     * @return
     */
    public ResponseData success(){
        return new ResponseData (Status.SUCCESS.Code,Status.SUCCESS.msg);
    }

    /**
     * 默认的失败
     * @return
     */
    public ResponseData error(){
        return new ResponseData (Status.FAIL,Status.FAIL.msg);
    }

    /**
     * 成功 + 返回的成功信息
     * @param data
     * @return
     */
    public ResponseData sussess(String data){
        return new ResponseData (Status.SUCCESS,Status.msg,data);
    }

   
}

 二.常用变量类，根据业务需求可自定义增加或删除

public final class RspCode{
 
 
	    public static final String MSG 				    = "msg";
	    
	    public static final String DATA				    = "data";
	    
	    public static final String SUCCESS              = "success";
	    
	    public static final String OPER_FAILD			= "操作失败";
	    
	    public static final String OPER_SUCCESS			= "操作成功";
	    
	    public static final String ADD_SUCCESS			= "新增成功";
	    
	    public static final String UPLOAD_SUCCESS       = "上传成功";
	    
	    public static final String UPDATE_SUCCESS       = "更新成功";
	    
	    public static final String DELETE_SUCCESS		= "删除成功";
	    
	    public static final String ADD_FAILD		    = "新增失败";
	    
	    public static final String UPLOAD_FAILD         = "上传失败";
	    
	    public static final String UPDATE_FAILD         = "更新失败";
	    
	    public static final String DELETE_FAILD		    = "删除失败";
	    
	    public static final String QUERY_SUCCESS		= "查询成功";
	    
	    public static final String QUERY_FAILD			= "查询失败";
	    
	    public static final String ID_ISEMPTY           = "this id is Empty!";
	    
	    public static final String PHONE_EXIST			= "手机号已被使用！";
	    
	    public static final String IDNO_EXIST			= "身份证号已被使用！";
	    
	    public static final String PHONE_NOTEXIST		= "该手机号未注册！";
	    
	    public static final String CODE_FAILD			= "验证码错误！";
	    
	    public static final String CODE_OVER			= "验证码超时！";
	    
	    public static final String CODE_REPEAT			= "请勿重复发送验证码！";
	    
}

三、用法实例

public ResponseData queryUserInfo(@RequsetBody Map<String,String >){

        ResponseData  result= ResponseData.success();
        String resultCode = "0";//成功
        String message = "用户信息查询成功"；
        result.setResult_code(resultCode);
        result.setMsg(message);
        return result;
   
}
